Science Vocabulary Flashcards

Flashcards focusing on key vocabulary related to electrical circuits.

Ohm's Law

Resistance in a circuit is equal to voltage divided by current.

Equation of resistance

Resistance=voltage\current

Equation of voltage

Voltage = current x resistance

Ohms discovery

Ohm found that the current, voltage, and resistance in a circuit are always related in the same way.

Ohms observations

Ohms set up a circuit with a voltage of the 2 points on a conductor. He measured the resistance of the conductor and the current between those points. Ohm concluded that conductors and most other devices have a constant resistance regardless of the applied voltage.

Series Circuit

All the parts of an electric circuit are connected one after another along one path.

Parallel Circuit

Different parts of the circuit are on separate branches.

What are circuits made of

Batteries, energy, electric currents, a switch.

3 basic features that all electric circuits have

Devices that run on electrical energy, sources of electrical energy, and conducting wires.
